' vnppueauon prix z2, im, serial No. sensei I scum. ictus-zam This invention relates to a machine for carrotinu hatter's iur while it is still on the skin.` and has for an object to provide an improved and simpliiied means of uniiormiy and more il thoroughly applying the carroting solution to the iur and to prevent waste of carrotlns solution.

It is also an object to provide a machine which will effectively and more uniformly apply the carroting solution in such a manner as to sive 10 better Ielting of the fur than is secured with the usual hand operation.

With the foregoing and other. objects in view I have devised a construction as illustrated in' the accompanyingdrawing forming a part oi 15 this specification. It is however, to be understood that I am not limited to the exact construction and arrangement shown but various changes and modincations may be employed within the scope of the invention.

Fig. 2 is a side elevation thereof;

Fig. 3 is a transverse section substantially on 25 line 3-3 o! Fis. 1;

Fig. 4 is a top plan view of one end portion of the machine; and

Fig. 5 is a side elevation of one end portion oi the conveyor.

3@ Ille machine comprises a supporting frame I0 on which is mounted a movable frame Il. The supporting frame i carries a means ior applying a carroting solution to the fur on the Pelt M while the movable frame Il carries the means dior ileeding and holding the pelt vvvliile the car rot is being applied and worked into the iur. The Ieeding and holding means for the pelt comprises an endless conveyor or belt I2 running over suitable drums or sprockets il and il at w its opposite ends. This holder and conveyor may be ci different constructions and materials such as an endless rubber belt or it may be constructed oi a series of transversely extending narrow metal strips I secured at their opposite ends to M chains it running over the sprockets. This conveyor or belt must be o! some material which is resistant to the action of the carroting solution.. Rubber is fairly resistant, and the metal strips could be of resistant metal, such as stainless steel.

This endless belt carries a series of pins or prongs il suitably spaced and of sumcient length to penetrate the skin oi' the pelt and feed it during the carroting operation as well as hold it 55 in proper position, Immediately below the lower run oi the conveyor are a Series oi wires i8 extending longitudinally oi' the conveyor and closely adjacent the under surface thereof so as to support the pelt against the under surface oi the conveyor. 'A pelt, such for example as a 5 rabbit pelt, is shown just entering the machine at l! and another is shown at lila in a position` to be treated. The wiresv Il should be of a inaterial resistant to the carroting solution, such for example as stainless steel, and extend at 10 their opposite ends over suitably mounted transverse supporting bars. and are connectedto means 2i for individually adjusting the tension ot these wires. The frameli has laterally extending pins 22 seated in vertical slots or 15 notches 23 in bearing brackets 2l on the supporting frame i0. This holds the frame Il and the parts carried thereby against longitudinal movement but permits up and down movement to allow for adjustment to accommodate pelts of 20 different thicknesses and to insure uniform treatment of the iur of all pelts.

The carroting solution isapplied` to the fur of the peit by a brush -iocated under the lower run or the conveyor I2. At its lower edge this brush 25 runs in a container 2B holding the carroting so- Y lution 21, and the level of this solution is mainl t tained constant by any suitable means, such for example as an extension 28 commenting with l this receptacle and holding a bottle 29 containu 30V ing the solution in the inverted position which,k

as is well known, will automatically feed solo tion from the bottle to the container and maintain the liquid level therein at the level of the lower end of the-neck of the bottle. To the rear of the bmsh 25 isanother rotating brush 30 and to the rearoi the brush Sil-is a third rotating brush el. An inclined pan 32 under the brushes I0 and 3| returns any carroting solution which y may be dropped by the brushes 30 or 3i back to 40 the receptacle 2B so that it is not wasted.

The conveyor i2 is moved in the direction of the arrow 33 so that the lower run of this conveyor moves to the left as viewed in the drawing. The peas indicated at is are fed in between this conveyor and the supporting wires is and' this may be done from a convenient feeding table 3|. 'I'he pelts are fed into the machine with the fur side down and tail end first so that the natural lie of the fur is in the direction oi' 50 movement of the pelt through the machine. The pins orprongs il penetrate the skin oi the pelt and slide it along on top of the supporting wires il. rst over the brush 25 and then over the brushes 3l and!! in that order. As the pelt is v55 carried over the brush 25 the carroting solution is carried from the supply 21 by the bristles of this brush and applied to and rubbed into the fur of the pelt, and the brush 25 is rotated clockwise as indicated by the arrow so that the bristles of the brush move in a direction opposite to the direction of the movement of the pelt and also opposite to the direction of the natural lay of the fur so that the carroting solution is more evenly and thoroughly applied to the fur. This brush therefore brushes up the fur and applies carroting solution to it right down to the skin. As the pelt advances after the carroting solution is applied to the fur it comes over the brush 38. This brush Il also rotates clockwise so that its bristles move in a direction opposite to the direction of movement of the pelt and opposite to the direction of natural lay of the fur on the pelt. This brush is to work or rub the carroting solution which has been applied by the brush 25 thoroughly into the fur and right down to the skin, and also to spread the carroting solution so that it is uniformly applied to all of the fur. Then as the pelt further advances it comes under action of brush Il. This brush Il, however, rotates counterclockwise or in the opposite direction to that of the brushes k and 25 so that its bristles move in the direction of the natural lab' of the fur. This brush slicks and lays down the fur in its natural position on the pelt and also removes surplus carroting solution. As previously indicated the frame Il carrying the conveyor and the supporting wires is free to move up and down and therefore to yield to pelts of 'different thicknesses and also to insureuniform treatment of all pelts. Above the lower run of the conveyor and in line with each brush there may be a backing up roller to back up the flexible conveyor and prevent its yielding out of position under pressure of the various brushes. The brush 25 is preferably somewhat larger than the brushes I0 and Il. Brush 25 may be about 9" in diameter and brushes 3U and 3| about 6". 'I'he bristles may be mounted on bars l tapered and slidable from one end into suitably shaped grooves in the center drum so the brushes may be easily renewed as they become worn or are eaten away by the carroting solution. This arrangement may place the bristles in spaced clumps or rows as shown and therefore in order to make a smoother action the clumps of bristles on one-half the ybrush may be staggered in relation to the other half as shown in Fig. 3. With this arrangement bristles are in engagement with the pelt at all times.

It will be seen that as the pelts are supported by the wires il and the skin is punctured by the pins il these elements together effectively hold the pelt against being shifted out of position under action of the brushes, and it will so hold the pelt against shifting in either direction that it can be thoroughly brushed and operated on by the brushes operating in either direction without the pelt being dislodged or forced out of position. This combination also makes a very effective means for feeding the pelt at a uniform speed during the brushing and treating operation.

At the outlet end the pelts may be carried over the supporting means for the wires by means of a suitable apron 36, and there is also provided a series of stripping fingers Il to strip the pelt from The various brushes and the conveyor may be driven by any suitable driving means. One form is shown diagrammatically in Fig. 2 comprising an electric motor 38 driving the brush 25 by a suitable chain drive 39 running over sprockets 40 and 4i. The brush 30 may be driven in the same direction from the shaft for the brush 25 by a chain drive 42 running over suitable sprockets, and a similar chain drive 43 may be used for driving the conveyor belt i2. As the brush 3| must be driven in the opposite direction from the brushes 25 and 20 the motor 38 may drive a pair of spur gears M driving a sprocket for a chain drive 45 for the brush 3l.

Important features are the series of wires It supporting the pelt under the belt or conveyor carrying the prongs l1 so that the pelt is positively held and fed forwardly the carroting solution is applied and worked into the fur by the brushes 25 and Il rotating against the natural lie of the iur, plus the brush ll rotating in the opposite direction to lay and slick the fur and remove surplus carroting solution, This gives a better result than hand carroting as it is more thorough and uniform as the carroting solution is applied uniformly to all parts of the pelt and is also worked into the fur uniformly throughout the entire area of the pelt. This prevents applying too much solution in some parts and too little in others, saves carroting solution, and gives a better felting fur. It is also much easier on the operators as all they have to do is to feed the pelts in tail end first with the fur side down as indicated.

Having thus set forth the nature of my invention, what I claim is:
